GAS-DRIER.

Specification of Letters Patent.

llatentedl Apr. 3d, 1918.

Application filed December 8, 1915. Serial No. 65,674.

T 0 all whom it may concern Be it known that I, I-InnMANn A. BRAS- snn'r, acitizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas-Driers, of which the following is a specification.

My invention relates to apparatus for purifying and washing gas, and has particular reference to novel gas washing device of the vertical type.

In my application, Serial No. 36,818, filed June 28, 1915, I disclosed gas washing and drying apparatus which was found to be very eiiicient in service. However, in many furnaces there is not sufiicient space to permit of the use of a horizontal drying apparatus between the gas washer and the gas mains which feed the stoves and boilers. The present construction is designed to meet the ditliculties encountered in such situations.

In the present construction I have made use of the principle of centrifugal force, to the end that moisture which is carried in suspension in the gas is thrown outwardly against the shell of the washer, and allowed to trickle down to the lower end thereof. In

addition to the separation caused in this manner, I prefer to employ one or more rows, or series, of wooden baffles placed vertically, and between which the gas must pass on its way to the outlet. These battles are set at an acute angle to the line of motionof the gas, to the end that the moisture is caused to impinge thereagainst. In addition I provide a plurality of sprays, whereby all the surfaces on which deposits may be made may be flushed, or cleaned, at proper intervals.

The invention will be more readily understood by reference to the accompanying drawings, wherein Figure 1 is a vertical section through a gas drier constructed in accordance with my invention, and

Fig. 2 is'a" section on the line 22 of Fig. 1, the view being somewhat enlarged.

In the drawings it will be seen that I have provided a vertical cylindrical casing 10 having a tangential gas inlet 11. By reason of the location of this inlet, the gas is caused'to whirl in the casing, the centrifugal force tending to throw the particles of entrained moisture in the gas against the walls of the casing, down which the moisture trickles to the conical lower end l1 of the casing. Located axially within the casing is an outlet pipe 12. the lower end 13 of which is slightly flared. Mounted between the lower end of the flared pipe 13 and an apron, or flange, 14, projecting inwardly from the casing, are two series of bafiies 15, 16, one series being located concentrically within the other. These ballles are placed in close relation to each other, and the battles of the two series are located in angular relation to each other. It will be noted that the bullies 15 are arranged at an acute angle to the line of motion of the gas, which is indicated by the arrow in Fig. 2, whereby the gas is caused to impinge sharply against the baflles and to deposit thereon any entrained moisture, which trickles down the bafiies and immediately leaves the path of the gas. Likewise, after passing between the baffles 15, the gas must again change its direction, being caused to impinge against the baffles 16. The gas then passes upwardly through the outlet pipe 12 to the point of SO. 4

Located at the proper point within the casing are sprays for removing any accumulated solids. F or instance, I provide sprays 17, at the upper end of the main casing, sprays 18 at a point opposite the outer baflles, and sprays 19 inside of the inner series of battles. I may likewise provide a spray 20 in the outlet pipe. It will be understood that these are only operated at intervals, say once a day, in order to wash down any accumulations and keep the passages free.

he baffles which I prefer to employ are composed of wood, although baffles made of metal, either plain or corrugated, may be employed without deviating from the scope of my invention. I P

Other modifications may be made, and such modifications as are within the scope of my claims I consider within the spirit of my invention.

I claim;

1. In a gas drier, the combination of a vertical casing, a concentric pipe mounted within the casing, a circularlyarranged row of baiiles depending from the lower end of said pipe to change the direction of flow of the gas, and a water seal at the lower end of said casing, substantially as described.

2. In a gas drier, the combination of a vertical casing having a tangential inlet, a vertical pipe within said casing, said pipe being axially arranged, and a plurality of rows of bafies arranged in circular form and projecting downwardly from the lower end of said pipe to change the direction of flow of the gas, and means projecting inwardly from the wall ofsaid casing for assisting in supporting said baflies, substantially as described.

3. In a gas drier, the combination of a Vertical casing having a tangential inlet near its upper end, an outlet pipe extending vertical casing having a tangential gas inlet near its ,-.upper end, an outlet pipe projecting downwardly within said casin a plurality of concentric rows of vertical affies located closely adjacent to each other and depending from the lower end of said outlet pipe to change the direction of flow of the gas, and the bafiies of one row being placed at an angle to the baiiles of the adjacent row, means for intermittently spraying the inner and outer surfaces of said bafiles to remove deposits therefrom, and means for spraying the inner walls of said casing substantially as described.

Signed at Chicago, Illinois, this 2nd day of December, A. D. 1915.
